GOMBINED SPRING CAP AND TRUCK BOLETER-COLUME' GUIDE.

Application filed Uctober 31, 1921. Serial No. 511,640.

To all whom it may concern:

Be it known that we, RALPH V. SAGE andv GEORGE E. TnAon'nAY, both citizens of the United States, and residentsof the city of bolsters for railway cars, and particularlyto the end portions thereof, and we provide a member secured toand forming part of the bolster which serves as a top spring cap and spring seat for receiving and holding the springs and from the bolster thereto, while integral e2;- teneions thereof form column guides for the up and down movement of the holster, which are adapted to contact with the columns of the truck side 'frame in order to maintain the bolster in position during its movement .on the springs, and our. construction also provides a strengthening and stiffening member for the end of to distribute the load properly over the end of the same.

()ur construction is applicable to bolsters of what is known as thebath-tub type, the lower parts of the end portions of which are narrower than the upper portions, but may also be applied to bolsters of any other types as may be readily understood.

Having thus given a general description of our invention, we will now, in order to make the matter more clear, refer to the annened sheet or drawings, which forms part of this specification, and in which like characters refer to like parts.

Figure 1 is a side elevation of a portion of a truck side frame with the end of the truclr bolster in one of its normal positions, illustrating the application of our invention, Figure 2 is side elevation of the end portion of a bath-tub holster with our 1mproved spring cap and truck bolster column guide attached t' ereto; Figure 3 1s a bottom plan view of the spring cap and truck bolster column guide detached from the bolfiior transmitting the load the bolster and serves ster end; Figure 4 is a vertical longitudi nal sectional elevation of the spring-cap and truck bolster column guide taken on the line IV-IV of Fl ure 3; Figure 5 is a top plan view and igure 6 is a side elevation of our spring cap and column guide.

Referring now to the characters of reference on the drawings :--1 is a truck side frame which is shown of cast metal construction, but may be of any of the usual forms of truck side frames; 2 is the bolster illustrated of bath-tub ty e, but our invention may be applied to ot er types as well; 3 is our combined spring cap and truck bolster column guide as a whole; 4 are the bolster springs shown as a nest of live springs for lngh capacity freight cars, but we may adapt our construction to receive more or less springs; 5 are the truck columns of the 6 are the column guide porside frame; tions of our construction which may be provided with flanged sides 7, and 8 are rivets which secure our combined spring ca and truck bolster column guide to the si es of the bolster. Lateral strengthening flanges 9 are also provided to strengthen and stifien the column guides as illustrated near the bottom and similar flanges 1() are also provided near the upper portion, The lower surface of ouricombined spring cap and truck bolster column guide is'provided with spring pockets 11, which are surrounded by the downwardly extending flange 12 in order to provide a recess in which the upper ends of the springs are seated, and the flange 12 assists in holding them therein. We also further provide bosses 13 which extend downwardly from the spring seat and project within the central openings of the helical springs in order to further-hold them laterally n position. The spring cap illustrated is adapted to receive five helical springs, but its form or size may be moditied to receive four, six or any number desired. We also provide holes 14 through which rivets 15 pass to further secure our construction to the bottom of the bolster end. In order to further strengthen the structure we provide ribs or flanges 16 extending inwardly from the flat end portions of the column guide, which, however, for the urpose of ease of construction and asse'm ly, do not bear against the sides of the holster, but at the same time stifien the column guide portions. We also provide other similar stifiening flanges 17 as illus trated.

The entire construction of our combined plied maybe-of substantially uniform size,

7 column .tegral construction,

thusadapting theconstruction for use without materially changing the size of the bolster, as suchchange requires different and costly pressing dies to form bolsters of different sizes, and this isobviated by our construction..

Although. we have shown and described our invention in considerable detail, We do not wish to be limited to the exact and specific details thereof as shown and described,

but may use suchmodifications in, substitw tions for, or equivalents thereof as are embraced within the scope of our, invention or as Ipointed out in the claims.

aving thus described our invention,'whatwe claim and desire to secure by Letters Patent is:

L-The combination with a bolster, the lower end portions of which are narrower- ,than the upper portions of the bolster ends, of a spring cap and column gulde 'secured'to the end portion thereof, comprising a plate 1 portion under the bolster end provided wiih spring pockets in its lower surface and with integra column guides, said late portions and column guides extending aterallyfrom the bolster end.-

2. The combination with a bath-tub bol- Star, the lower end portions of'which are narrower than the upper portions of the bolster ends, of a combined spring cap and end portion thereof and comprising an inincluding a bottom plate provided with a spring recess and spring retaining bosses,

guide mounted and secured on the column guides extending outwardly and laterally therefrom, and

ster ends, of a springica-p and column guide secured and mounted 'on.the end thereof, comprising .a-spring cap having a downwardly extending 'ma-rginal flange adapted tosurround theupper portions of-the outer springs, a plurality of downwardly extending bosses adapted to be seated withinvthe spring openings-to'assist in retaining them in position, column guides extending out wardly and laterally from each side and provided withstrengthening ribs, all formed integrally.

. 4. An integral combined spring cap and column guide mounted on and secured to the end of a bath-tub bolster,-the lower end portions of which are narrower than the upper portions of the bolster. ends, comprisinq a substantially flat lower portion adapted to contact with the bolster end having a spring pocket on its lower surface of greater width than the lower portion of the bolster. end and other integrallatera'lly extending portions provided with rooves, and adapted to act as a column gui e.

end, com rising a substantially flatflower portion, t e upper surface of which contacts ,with the lower-portion of the bolster end 1 and is provided with a spring pocket on its lower surface surrounded by amarginal flange, in outwardlyand laterally thereof and provi ed with end grooves adapted to co-operate with the truck columns, and inner and outer strengthening flanges formed integral therewith.

.In witness whereof we hereunto afiix our signatures. 1
